Nothing, get it fixed properly or replace it. A 04 most likely needs replaced. Putting in a stop leak usually causes more problems than it cures in todays vehicles, that stuff was designed for big rig with monster cooling systems, if it is used in a small rig it tends to plug up vital cooling passages in the engine, heater cores and small core radiators.

Agreed, a Radiator can be had for $100 if you have a friend do it for you. Get new hoses and clamps too.


Just changed one on a 2003, probably the same. Total time once I began, about thirty minutes. Be careful of the transmission line attachments when you reattach. Gorilla strength not required or you could bust the new radiator. Just check for tranny fluid leak at radiator after test drive. Tighten just enough to stop the leak, if there is one.
